Application led Novembeir, 1919. Seriall No. 339,261.

` To all iff/0722, t may concern Be itlniown that I, HEiNRicH Booirisoi, a citizen of @Zeche-Slovakia, residing `at Poughkeepsie, in the county of Dutchess'and State of New York, have invented certain new'and usefiillmprovements in Automatic Musical instruments, of which the following' isa specification.

This invention has relationto recordcontrolled musical `instruments of the kind set forth in Patents Numbers 1,197,573; 1,197,57 and 1,197,575, issued September 5, 1916, to Heinrichockisch, Assignor to M. Nelte & Sons, of New York, N, Y., a corporation of New York, and also set forth invmy companion application Case A for patent Serial Number 339,260, ledof even date and application Case C to be filed later. y y

In 'other words, this invention is a furn ther particular embodiment of amechanism wherein there is a plurality of series, or scales, of tone emitting elements, as organ pipes for eramplefone of saidrs'eries being; for tones having a' different quality `than the other, as pedal andmanual for instance,

and record controlledmeansv forselectively causing the operation of any one or more or4 the tone emitting elements of either series' aloiie`,or of any one ormore of the elements of oneseries in combination with any one or more of the elements of theother series.

The embodiment illustrated in the ,accom-4 panying` drawings comprises many parts and correlations of parts which are nerically similar to what has been shown, described and claimed in my patents here# inbefore named. Moreover,` it comprises parts and correlations of parts which are specifically identical with parts and correla-` I tions of parts set forth and claimed in my said companion application of even date herewith.

The new features upon whichhthe presentl application is based are exemplified `by the s mechanism herein illustrated for carrying the movable members embodied in thetone connections and for operating said members from the primary operating pneumatics. In

i this invention the movable members referred to are 'carried by circuit closing devices and each series of said circuit closing` devices and members (that is to say, the series of circuit closing devices and members for one scale `of tone emitting elements, and simi larly, the series of levers and members for the other scale of tone emitting` elements) is provided with an operating member common thereto.

rllhese operating members act through'` the respective series of levers to thereby move said members into engagementy with corresponding elements of the tone conneet-ions, the said corresponding elements in ythis application, as inmy before mentioned companion application, being, preferably,

contact wires arranged in pairs and forming parts of electrical tone circuits and the said movable members being, `in 'such case, elec trical circuit' 'closing elementsforbridging the spaces between the pairs of contact wires,

respectively. The movable operating mem-' bers for the series of levers, `res n ectively, are provided with elements of a yie dable nature to `enga-ge the levers, respectively, and these form `one of the' new features in this emby which the `relative pneumatic forces which `control the primary operatingl pneumatics are controlled from the respective record controlled primary control valves.

Having thus in a general way set forthy rthe relationship or this embodiment to other embodiments whichy have been made the subject of generic claims in my lpatents and application for patent hereinbefore referred to, I will'in following portions of this specificat-ion set forth this embodiment somewhat minutely both as regards the old and the new features thereof, withoutintending1 thereby to restrict the invention to the particular details set forth', asv changes in the details 75y bodiment of the invention. Another of the may be made without departing from the spirit of the invention as defined by the appended claims.

In the accompanying drawings, wherein like characters of reference denote corresponding parts in the several views:

Figure 1 is a diagrammatic view of a system which exemplifies the preferred embodiment of the present improvements;

Figure 2 is a perspective view of the part of the switching mechanism involving novely features, arbitrarily assumed, as shown by the reference characters thereon, to bein` eluded in the pedal scale, but as the manual scale embodies a part of identically the same construction, it is apparent that this view similarly illustrates the corresponding parts in said manual scale; y

Figure 3 is an end view of the same parts of the switching mechanism, showing the position thereof when the circuits in the pedal portions of the mechanism are interrupted, i. e., when bridging members are out of contact with contact wires c;

Figure a is a vertical section through the same parts, showing the positions of the elements when circuits in the pedal scale are completed Figure 5 is a plan view of the switching mechanism arbitrarily assumed to be for the pedal scale but equally illustrative of the manual scale;

Figures 6, 7, and 8 are views of different portions of the note sheet preferably employed as the record to control the operation of the instrument.

D is a tracker boardhaving tone ducts 12 common to a plurality of scales, a manual scale and pedal scale, for example, and also having control ducts 1 and 2.

1&1 designates a primary tone valve whose stem is connected to a membrane 17 mounted between a chamber 13 and a suction conduit 131", the valve itself being mounted in a chamber, 1a, having a suction port 2O and an atmospheric port 19. In practice there is one of these valves, membranes, chamber 13, and chamber 14a for each note common to both scales, and additional valves, membranes and chambers for each note which is to be played in the manual scale only, for example. As this invention is concerned only with those notes which are common to a plurality of sales, the description will be confined to the parts by which the sounding of the notes in either scale alone, or in roth scales together, in any combination called for by the musical composition, is permitted, notwithstanding theuse of primary tone valves and tone ducts common to both sales. lt will be understood that the several chambersl and 14' are, in practice preferably embodied in a chest (a section of which is shown at K) called primary tone chest, and that the conduit 13, also in said chest, may be common to the several valves 14; and membranes 17 and suitably connected with a means for attenuating the air therein. The ducts 1Q are connected to the chambers 13, respectively, and serve to admit atmospheric air to the membranes 17 to thereby move the primary tone valves 14 to close the atmospheric ducts 19 and open the suction duct-s 20. Each section of the chest K also has a pneumatic g3 provided with primary tone contacts g2, respectively, for closing tone circuits hereinafter fully set forth.

F and H designate secondary operating pneumatics, having suitable connections, such as indicated at F and H, for example, with the stems c2 of valves (not shown) in the manual and pedal wind chests as in my patents and applications for patent hereinbefore referred to. In practice, there is one pneumatic F for each valve in the manual wind chest section and one pneumatic H for each valve in the pedal wind chest section.

Each pneumatic F is connected to a chamber G3. These chambers 63 are, in practice, preferably formed in a secondary tone chest, a section of which is shown at I in Fig. 1. Similarly, each pneumatic H is connected to a chamber G3 and these several chambers 68 are preferably formed in a secondary tone chest, a section of which is shown at I in Fig. 1.

Each chamber 63 is provided with a secondary tone valve 70, and is formed with a suction port 641 and an atmospheric port 65. rlhe valves 'TO are severally moved to close the respective atmospheric ports 65 and open the respective suction ports (Se and thereby collapse the corresponding pneumatic F or Hby admitting air at atmospheric pressure to chambers 66 having membranes 67 connected to the valves T0. This air is admitted to said chambers G6 through ducts 69 and these ducts are opened and closed by valves (5S carried by the armatures f', z/ of electro-magnets j and it which are included in the tone circuits hereinafter fully set forth.

The control ducts 1 and Q hereinbefore` referred to respectively lead to chambers 3 and 3"* formed in primary control members J and J The member' J also has a suction chamber 4f, a valve chamber 5, a suction port G, an atmospheric port 7, a valve 8 in the chamber 5 to control said ports, a membrane 9, mounted between the chambers 3 and 4 and connected to the stem of the valve 8, and a pneumatic having connection with the valve chamber 5, through a port 10, and provided with a contact member Zr". This member J, in the herein illustrated arrangement of the parts acts, through intermediate mechanism hereinafter described, to close the circuits through the magnets h, to theretones or ettects alone are to loe sounded, pneumatics E are expanded, 'thereby roclo ing shailfts p3 and removing the pressure of cams p4' from the rock arms 1) and allowing said arms to turn piyotally and permit the member l) to recede from the circuit closing devices (Si and the latter (except those which are re t .'ained against such movement as hereinaiter set forth) to move by gravity, for example away trom the conw tact wires (Z, CZ.

The interior ol the primary operating pneumatic element E for the manual is con nected by a duct Q4.; with a ch amber having suction port LGil and an atmospheric port @(92 il secondary valve mounted in this chamber and is arranged to open the suction port and close the atmospheric port, or to close the suction. port and open the atmospheric port. The first named position Ais its normal one, and hence pneumatic E is normally collapsed through duct 24, chamocr 2", port 2o, and suction chamber 26C. To hold the valve in this position (and to provide lor its being moved theretrom to close suction port 26"" and open atmospheric port 2Gb when pneumatic ffl is to he expanded), l provide a membrane fl? which arrangei'l between two chambers 2i and 2T", one of which chambers, as 2lb, is always under suction. being` connected to suction chamber 26C by channel Qayhile the other chamber, Q7, is .normally 'under atmospheric p essure which is exerted against the membrane 27 in a direction to hold the *faire Q5 away trom the suction port 2G and over the at inosphenfie port 2Gb. T he chamber 2T is connected by duct QT with a chaniber 28 h a ving` an atmospheric port 28:" and a suction port 98h. ln this chamber 28 there is a subprimary control Valve 2f) arranged to close the suction port 2S" and open the atmosphcric port 28, and vice versa.. The former is .its normal position and hence chamber 2T is normally under atmospheric pressure, as set torth. The yalye Q9 has its stem Q9 connected to a membrane 80 which is arranged between a suction chamber 31 and a chamber 3Q, the latter chamber haring an atmospheric duct 33 which is controlled by a val 34 on the armature 35 oit an electro magnet 3T.

lt will be amparcnt that when the niagnet 3T is not energized the duct Will be closed by the valve 34 and that when said .magnet energized it will attract its armature, thereby opening the atmospheric duct 33 and admitting` air at atmospheric pressure to 'the chamber 3Q, whereupon Yalye 29 will be moved and will close the atmospheric port 2S and open suction port QSb. Chainloer 27a will new be under suction and as chamber QT always under suction, it follows that the pneumatic, 'forces on opposite sides oit the membrane 2T will counterbalaiice each other,

and Valve 25 will tall and open atmospheric port 2Gb and close suction port 26, Whereupen 'the pressure Within pneumatic element lil 4will equal the external pressure exerted on the moya-ble board thereof, thereby permitting the spring E ot said pneumatic to expand it 'tor the purpose already explained.

hilagnet 3i" is energized tor the purpose set lorth from one ot the primary control ducts, duct Q for example, through the primary control member J', whose Valve 8a is normally in such position that the pneumatic c is expanded, but which Valve when its control duct is opened is moved to close atmos'oheric port 7 and open suction port o, thus collapsing pneumatic c and moving its contact e5 into bridging relation with contact Wires c, fr, thereby closing an electric circuit, tlnough the magnet 37. This circuit, which is called manual control circuit may be traced diagrammatically as follows:

From a suitable source of electrical potential, indica-ted at l?, by Wire and branch w to contact Wire 002, thence through contact c5 and rontact Wire and Wire fr" to the magnet 3T, and Ytroni said. magnet by Wires m5, fa, and 007 to a terminal m8 in a negative bus bar X and back to thc source P by the wire sa.

Substantially similar connections are, or may be, employed to expand and contract the primary operating` pneumatic element Gr for the pedal scale, arranged, however, to

keep said pneumatic element in normally expanded condition. The magnet for the pedal member oit the switch, marked 49: the remaining elements tor said member are designated as follows: o8, secondary control valve; 39, secondary control-valve chamber; 39, suction port to secondary valve chamber; 39', atmospheric port to secondary control valye chamber; 40, membrane connected to the stem 38@ of the secondary controlvalve; 4l and 4l chambers on opposite sides oit said membrane, chamber 4lb being constantly in communication with the atmosphere; 4lc a duct extending from chamber 4t and through which said chamber is normally in communication with. the atmosphere; 42, chamber 'for subprimary control valre- 42 and 42h, atmospheric and suction por respectively to said chamber; 43, subprin'iary control-valve; 43 its stem; 44, membrane connected to said stem; 45, suction chamber on one side ot the membrane; 4G, chamber on the other side ot the membrane; 47, atmospheric duct leading to the latter chamher; 48, valve for opening and closing said duct; and 49, armature to which said valve is connected.

lt Will he apparent that when magnet 49 is energizied, valve 4S Will be raised, thereby opening duct 47 to the atmosphere, thus llO causing `valve 43 to open'suction porti/42b and close atmospheric port 4 a The air in chamber 41f4will nowl be attentuated from chamber 45, (through chamber 45, `port 42", chamber 42k and duct 41C) and, as the pressure of the air in ,chamber 41b remains atmospheric` will follow that the. secondaryl control-,valve 38 will be raised `and will open suction port 39a' and close atmospheric Y,port 89. Pneumatic elements Gwill now be under suction and will collapse and rock the shaft g3 resulting, through the elements already set forth` inthe raising of the en- ,tirel series of circuitclosing element g- (eX- cept those which areV restrained against' such movement, as'hereinafter set forth) Y intov engagement withv the respective pairs of contact wires c,y c.

rThe magnet 49 is energized from the coni trol duct `l, through the' primary control j member J, lwhose valve 8 normally in such position thatvthe pneumatic Hb? is ex- .matically as follows way of wires m6 and m7 to the negative'biis` bar Xfandthence back, throughwire m9, to the source P.

to adjust the circuit closing'elements cj into bridging engagement with" contact wires c c to include pedal tones orV effects with' manualtones'or effects occurs immediately prior'to the opening of the ducts-12 for-the notes to be affected. Moreover, the energizing of these magnets 37 and 49 ceases at the moment the duct or ducts 12for the tones to be affected. are opened.` ,The energizing of magnet 49 or magnets 87 and 49 accordingly are preparatory functions tending to result in the collapsing of the operating pneumatic elements G and the moving ofsall circuit closing elements ginto bridging engagement with contact wires c, c',

i when magnet 49 is energized and the movingv` of all of said contacts'out ofengagement with said wires lwhen the circuit to this magnet is broken, and, similarly, tending to result in the expanding ofthe operating pneumatic elements E and the moving y of all circuit closing elements e out ofbridgingA engagement with lcontact wires d, d',

The operation, of energizing magnet 49v` `stantially identical iviththat shown scribed in my beforementioned application.

with said wires when .the circuit to the latter magnet is broken. i I j j This tendency, however, as will'be readily seen by those who are familiarwith my inventions relating to the automatic control of mechanisms of this nat-ure.' musty be resisted or rendered non-effective with relation to the contacts corresponding toftone ducts which are openy at the moment either controll duct is open, to thereby assure the maintenance of the tonesy for the full vlength of time their "respective tone ducts 4are open, uninterrupted by the opening of either control yduct to affect i succeeding tones. j y f `For this reason. in this particular embo'diment ofthe invention, l employ the v fhereinbefore described series of'independently pivoted circuit closing devices Gland 58 and provide individuallyyieldable supporting elements or connectionsbetween the operating-.members Pand Q andthe circuit closing devices and further provide locking elements, as vpneumaticsf and 77, for

j example, which are controlledl from the tone circuits, hereinafter set forth, and hencev are maintained vin locking engagement with the respective circuit closing devices 58, l61,

from the moment the corresponding tone The preferred forml of yieldable connec` tions employed between each circuit closing devices 58 and common operating member Q for the series of devices 58 and between ,each circuit closing device Gland thel oper-l ating member P common to theyseries of devices 6l is shown best in Figures 3 and 4,

uit being understood that while these figures represent characters which indicate them as illustrating part Oithepedalr scalemechanism,`they nevertheless .also illustrate corj kresponding parts ofy the'vmanual scale, as `the structure of these two parts, i. 'el of the pedal and manual c scales, isy or may be identical.l Upon reference y to these ,iigures it will be lseen that the operating mem,--

ber `P (orQ) has `a chamber 50 which receives the stem. -51 of a holding element having a head 52 to engage theunderside of j the corresponding contact lever 58 (orl).`

`The chamber is vprovided with aspring 52 which encircles the stem 5l and `said stem is providedwith a collar 53 forming an abutkment against which the spring presses.

Each circuitclosing device 58j, 6l isprefer- -ably 'provided withl a retracting spring 54.`

The locking mechanism here shown is sub-y and defor patent, of even date herewith. The lockl yingpneumatics 75 of the pedal section `have projections 76 to engage projections 76a from the contact levers 58, respectively, and,.simi

jlarly, ythe lockingwpneumatics 77 of theY `throu gh manual section have projections 78 to engage projections 7 83 'from the levers 61, respectively.

For each pair of locking pneumatics 7 5, 77--that is to say, for each pneumatic 75 of the pedal and the pneumatic 77 tor the same note in the manual-there is a valve 84 which is mounted in a chamber having a suction port 82 and an atmospheric port 82a. Each chamber 83 is connected by ducts 79 and 8O with the correspondingpair of lockincr pneumatics 77, respectively. The valves 84 are moved individually to close the corresponding atmospheric ports 82a and open the corresponding` suction ports 82 by the admission of air at atmospheric pressure to respective chambers 87 having membranes 8,8 connected to the valves. This air enters the chambers through ducts 90, respectively, and these ducts are controlled by valves 92 carried by the armatures 91l of electro-magnets 91, the circuits ot' which are opened and closed from the respective primary tone valves 1%. Hence, the magnets 91 are in tone circuits so that the respective pairs of locking pneumatics 75, 77, are controlled by the tone circuits, as in my application hereinbefore referred to.

Accordingly, it will be seen that Whenever a tone duct 12 is opened, the corresponding locking pneumatics 75 and 77 are deflated and their projections 76, 7 S are moved into engagement with the projections 76, 78a of the corresponding,` circuit closing devices 58, 61, thus holding said levers in the position occupied by them When the corresponding tone duct 12 Was first opened and maintaining them in that position until said duct is closed. For example, when the organ is first started, and assuming that 'the first tone or tones are manual tones only, and hence all circuit closing elements c are in engagement with their respective pairs ot contact wires CZ, d and all circuit closing elements g are out of engagement with their respective pairs of' Contact Wires c, c, (neither control duct bein open at this time) the opening` of any tone duct 12 will complete the circuit the corresponding magnet 91, whereupon the corresponding; locking' pneumatics 77 and 75 will immediately collapse. The projection 78 from the collapsed pneumatic 7 7 will thereby move beneath the projection 7 8 of the corresponding circuit closing devices 61 and remain in that position until the tone duct is again closed: and, at the same time, the correspondingr pneumatic '7 5 `will collapse and its projection 76 Will move over the projection 76 of the corresponding circuit closing device 58 and will remain there until the tone duct is again. closed. Hence, circuit closingl element c corresponding to the open tone duct 12 cannot move out oit engagement With contact Wires (Z, d', nor can the circuit closing element g corresponding' to the same tone duct move into engagement with contact Wires c, c', un-` til said tone duct is again closed, even if control duct 1, or both control ducts 1 and 2, meanwhile are opened. Accordingly manual tones corresponding to tone ducts 12 which were opened before control duct 1, or control ducts 1 and 2, are opened, continue uninterrupted by the opening of said control ducts until the'tone ducts have been closed, the closing of said tone ducts breaking the circuits to the corresponding magnets 91 and changing; the tension oi? the air in pneumatics 75 and 77 to atmospheric, thus causing said pneumatics to expand and release the corresponding` devices 58`and 61. The control duets are opened in advance of the opening` oit the ducts 12 corresponding to tones which they are to affect and are closed shortly a't'ter said tone ducts are opened.

To introduce pedal tones with corresponding manual tones, duct 1 alone is opened, the manual mechanism being normally operative already stated, and if pedal vtones are to be played Without correspondingr manual tones, then duct 2 is opened to exclude the manual tones and duct 1 is opened at the same time to include pedal tones.

The opening` of contact duct 1 will result in the energizing ot magnet 49 and this in turn Will cause the operating pneumatics G to collapse, thus raising` the operating member Q and torcing` all circuit closing devices 58 (except those which are held by collapsed pneumatics 75, i. e., the lockingr pneumatics 75 corresponding` to open tone ducts) toward the Wires c, c.

The opening of control duct 2 results in the energizing of magnet 37 and this in turn will cause the operating pneumatic elements ll to expand, thereby releasing' operating;V member P, which is thus allowed to recede from the ivires (Z, tl, all the devices 61 'following this movement ot said member, except those which are held by collaj sed locking); pneumatics 77. lt will be noted that the springs 52 permitmovcment of the operating members Q and li relatively to the devices and 61 and are placed under tension il' their respective levers are held against movement toward the contact Wires c, c or (Z, d, with the operating members, so as to torce their several levers toward said wires, as soon as the levers have been released. be noted that the springs 54 are placed under tension when their respective devices 58 or 61 are held against movement away from the Wires c, c', or (Z, cZ, with the members P or Q, and become effective to retract said levers as soon as the latter have been released.

As already stated, the tone circuits are completed when the tone ducts 12 are opened, respectively, the opening of said ducts caus- It will also ingl the corresponding pneumatics g3 to colm lapse and move` their contact elements g2' into bridging engagement with the space be y tween respective pairs ot' Contact wires g" These circuits may be traced as to the corresponding terminal m8 on the nerrative bus bar and back to the source l. This energizes the corresponding -magnet 91 and delates the locking pneumatics 77 and 75. The magnets f are included in parallel `circuits which may be interrupted by movementoi' the contacts e away Jfrom the contact wires Z d and the magnets h similarly are in parallel circuits which may be interrupted by movement of the contacts g away from the contact wires c, c. As already stated these circuits form parts of the tone circuits. It neither of the control ducts has just been opened the tone will be sounded in the manual alone because the operating pneumatic elements E are collapsed andthe circuit closing elements e are in engagement with the contact. wires d fl. The several contact wires el are connected by wires x10 to the respective terminals g and the several contact wires d are connected by wires w17 "to one side of respective magnets f, the other sides of which 'magnets are connected with the negative bus'bar X. On the diagrammatic view the circuit lwould be traced as follows, when neither control duct l or2 is opened, namely: from the positive pole of the source P, by

`wire a' and branch m14 to contact wire y by bridge contact g2, contact wire g4; and wire m15 to. terminal ge; by wire 0016 to contact wire d; through circuit closing element c and contact wire d and'by wire m17 to one side of the magnet f; through said mag-` net and by wires :018, w19 and 007 to terminal x8 'in the negative bus bar X and backl to the sourceby way of wire m9. It control f duct l hasbeen opened, thereby energizing magnet 49 andresulting in the collapsing of pneumatic element and the bringing of circuit closing elements 'g into engagement with contact wires c, magnet It in addition to magnet .corresponding to open tone duct 12 will be energized. The circuit through magnet;c will of course be the same as that already described while the circuit through magnet it may be traced on the diagrammatic `view as follows: from the source to terminal g by the way already described; thence by wire m20 to contact wire c and through circuit closing element g and contact wire c and wire x21 to one side of corresponding magnet h; through said magnet and by wire w22 and Wire m7 to the negative bus bar Y. and back to the source.

lt pedal tones only are to be sounded, control ducts 1 and 2 will have been opened iimnediately prior to the opening oi the duct l2 Ytor the tone to be sounded in manual alone. Hence, when duct l2 is opened the portion of the circuit to the corresponding magnet j', between terminal gs and the nega-V tive bus bar X is interrupted as the corresponding contact hasbeen withdrawn from its engagement with the contact wires 65,03. It is believed that the invention will be fully comprehended from the foregoing description and. that it will be seen that I have provided a very simple and practicable switching mechanism by which, in short, the tones sounded may be manual tones alone, pedal tones alone, or both manual and pedal tones together, in any of the infinite vvariety of combinations oi such tones necin Figs. G, 7 and S of the drawings are marked 'n and its control apertures are marked a and n2. described.

would have it understood that the con struction shown and described is exemplary only and that many changes may be made in details without aiiecting its spirit or departing from the scope oitL the claims. In many generic respects this invention is like that oit my application before referred to. and in tlioserespects wherein the two are common the generic claims are embodied in the other application.
